Re: Accessing old DBM file with DBI - "write permission"?

in reply to Accessing old DBM file with DBI - "write permission"?

On the other hand, this works:

#!/usr/bin/perl -w use warnings ; use strict ; use DB_File ; my %h; unlink "data" ; tie %h, "DB_File", "data", O_RDWR|O_CREAT, 0666, $DB_HASH or die "Cann +ot open file 'data': $!\n"; print "Content-type:text/html\n\n"; foreach my $key (sort keys %h) { print "<br>$key -> $h{$key}\n"; }
But I get an empty result, no output. (Possible that's what's in the file, I suppose, but seems odd for a 65kb file.)

    Maybe you could try to create an empty DBM file and see how big it is on your system.

      In themeantime, I found a filepath that was wrong - so now this version works perfectly. Outputs 200 lines of pairs, as sort of expected.

      So, my needs have been solved - just the mystery of the DBI version for information left.
